C3PRO – Concrete 3D Printed Reinforced Objects

The aim is to establish guidelines for the use of 3D-printed reinforced concrete components in construction and open new possibilities for sustainable solutions. Together with Österreichische Bautechnik Vereinigung and TU Wien, the project is being carried out as a collective research project, in which 27 industry partners will also contribute their practical experience.

Building on the foundations of 3D concrete printing established in the previous project, C3PO, particularly with regard to material development and process control, C3PRO focuses on integrating reinforcement systems into extrusion-based additive manufacturing processes. This advancement enables the production of concrete components that are both load bearing and resource efficient.

The project focuses on developing automated manufacturing and design concepts that integrate digital planning, structural calculations, and manufacturing into a continuous workflow. Experimental investigations and prototype production are used to analyze load-bearing behaviour, manufacturing quality and material efficiency in depth.

Students on bachelor's and master's programs in civil engineering and construction management are also involved in the research project as part of their final theses. They actively support project work, contributing to the further development of additive manufacturing in the construction industry and fostering close links between research, practice and teaching.
